Product Description:

The AX2523-B200 is a two-channel servo drive from Beckhoff in the AX Digital Servo Drives series. It converts DC-link energy into controlled three-phase output for synchronous or induction motors used in positioning and speed-control tasks on automated machinery and material-handling axes. The unit combines current control, field-oriented regulation, and fast analog feedback so the host EtherCAT controller can close motion loops with minimal latency in decentralized cabinet installations.

During continuous operation, the drive delivers a rated phase current of 3 Arms, while short motion bursts can draw up to 9 Arms. An output current form factor of 1.01 indicates that the effective RMS value nearly matches the average amplitude, which helps limit thermal peaks in motor windings. The power stage supports loads whose winding inductance falls between 12 mH and 75 mH, allowing the amplifier to operate with compact servomotors or larger torque units. On the control side, the ±10 V analog command input uses 20 kΩ of input resistance, and the drive samples that channel through a sigma-delta converter. Internal commutation and current loops are updated against a DC bus clock so that each vector cycle aligns with the specified motor parameters.

The measurement front end provides 14-bit feedback resolution and refreshes it every 62.5 µs, feeding a current control loop that switches at 8 kHz. Thermal losses are 30 W at rated load and 12 W at idle, so cabinet ventilation can be matched to the expected operating condition. The mechanics occupy a footprint of 50 mm in width, 230 mm in height, and 240 mm in depth, which supports high-density stacking in standard 300 mm enclosures. Mounting hardware adds little mass because the module weighs just 1.7 kg, keeping handling loads low during panel installation.
